RIGIDFIX BOTH ENDS:CLINICAL OUTCOME OF ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION WITH QUADRUPLED HAMSTRING TENDON GRAFT AND BIOABSORBABLE RIGIDFIX

Abstract

Introduction: To report the results of quadrupled hamstring tendon autograft anterior cruciate ligament reconstruction with bioabsorbable Rigidfix fixation for both femoral and tibial tunnels.

Methods: ninety one patients were retrospectively identified by notes review as having undergone quadrupled hamstring tendon auto graft anterior cruciate ligament reconstruction with Bioabsorbable Rigidfix fixation with a minimum 1 year follow-up[range12 to 34 months] To our knowledge there has been no published results with Rigidfix device used as a method of fixation at both femoral and tibial tunnels

Results: Data were collected on 91 knees in 91 patients (100 %) at an average 13 months (range, 12 to 34) after surgery. They were all asked to fill in a subjective quetionaire. Seventy eight patients returned for clinical evaluation (85.7 % return) and subjective questionnaire was comleted by 78 patients (85.7 %).

The KT-2000 Arthrometer, mean side-to-side difference for manual maximum displacement was 1 mm (range, 0 to 3). Anterior compliance index mean side-to-side difference was1 (range −1 to 3), Quadriceps active displacement tests mean side-to-side difference was.5 [range −1 to 2]. The mean International Knee Documentation Committee knee score was 89 (range, 33.3 to 100).

Conclusions: Quadrupled hamstring tendon auto graft anterior cruciate ligament reconstruction with Bioabsorbable Rigidfix fixation is comparable with other methods of anterior cruciate ligament reconstruction in terms of patient satisfaction, knee stability, and function.
